Title: Mechanism for solving spherical triangles
IPC: G01C21/02
Filed: 1919-06-26
Abstract: 150,471. Wimperis, H. E., and Horsley, E. E. June 26, 1919. Spherical-trigonometry calculators. - The apparatus solves the triangle given two sides a and h and the included angle C and gives the third side c. The formula employed is Hav. o = Hav. (a - b) + Hav. C { Hav. (a + b) - Hav. (ab) } A pair of slides 23, 24 moving in parallel guides 43, 44 have slots 13, 14 perpendicular to the guides, in which work pins 3, 4, on equal crankarms 33, 34 which thus position the slides as set by a dial 73, Fig. 3, reading against a fixed pointer 77, and a pointer 74 reading against an inner scale on the dial. The slots 13, 14 are thus set at distances from a point along the centre line 0 2 proportional to Hav. (a + b) and Hav. (a - b) respectively. A bar 5 carrying pins 15, 25 working in the slots has a scale of Haversines along which a slide 65 can be set by a screw and milled head 55, so as to bring a pin 16 on the slide to a setting of Haversine C., the scale starting at the pin 15. The slide 65 has rotatably mounted on it around the pin 16 a runner 26 to position a bar 6 constrained by a parallel linkage 36, 46 to remain perpendicular to the base line 0 2 during movement. By this means the pin 16 is set on the base line at a point corresponding to Hav. C { Hav. (a+b) - Hav. (a-b) } The angle between the crank 36 and the base line is therefore the side c required, and is read off bv a pointer 18, Fig. 4, fast with the crank 36. To remove the dead centre difficulty a second parallel linkage 38, 28 is fitted to the pointer 18. To enable the sides a, b to be set directly on the scales on dial 73, a pointer 70, Fig. 5, may be fitted to move at half the rate of the pointer 74. A second form of the invention, employing the same principle, consists of a pair of slides 3, 4, Fig. 7, set along haversine or versine scales on a base 7, the slide 3 carrying an arm to which is pivoted at 15 a link 5 slotted to engage a pin 25 on the slide 4 and a pin 16 on a slide 26 moving on an arm 6, which is perpendicular to and slides on a base 8 parallel to the base 7. A milled head 55 and rackwork are used to set the arm 6. Setting of the sides or complements of the sides is made directly by slides 3 and 4 and of the angle by the slide 26, and the third side is read against a scale on base 8 by the slide 65. Cylindrical lenses are fitted to the slides to facilitate reading, and the slides 3 and 4 are set by means of milled heads 33 and 34 with screw and nut.

Abstract: 812,820. Coating paper webs; laminating. CHAMPION PAPER & FIBRE CO. June 6, 1955, No. 16180/55. Classes 96 and 140. A method of making laminated paper webs 106 comprises continuously applying an excess of fluid adhesive, e.g. dextrin, to one side of each of the laminµ but one, e.g. 92, 93, continuously doctoring off the surplus adhesive, pressing the coated surface of each lamina 92, 93 into contact with another lamina, e.g. 91 and 91, 92 combined respectively, pressing the combined laminµ 106 together under substantial pressure at spaced intervals along their path, holding the separate laminµ 91 . . . 93 and the combined web 106 under high and uniform tension from a time before application of the adhesive until the completion of the last pressing operation, the tension serving both to limit the amount of adhesive left on the laminµ after doctoring and to hold opposite sides of the web 106 in turn tightly against smooth convex cylindrical surfaces between pressing operations. In one embodiment, webs 91 . . . 93 are wound off rolls 94 . . . 96 under the control of friction brakes 97 . . . 99. The inner web 92 passes over an adhesive-applying unit 100 and is united with the web 91 between the rolls 101, 102, between which all the webs pass. The web 93 is next supplied with adhesive at 104 and united with the other webs around a roll 105 from which the laminated proceeds between the superposed rolls 107 . . . 110 to be wound on a roll 111. The rolls 101, 102, 107 . . . 110 are preferably metallic and one or more may be steam-heated, and the bottom roll 110, which is driven, may bear the full weight of the superposed rolls. The apparatus may be adapted to unite two webs only by omitting the web 91 and the unit 100 and delivering the web 92 direct to the nip between the rolls 101, 102 and, where three webs are being united, one of the webs may be introduced further down the stack, adhesive being applied to the appropriate web after its passage through one nip of the rolls. The number of rolls may be varied. The degree and uniformity of the tension are produced at least in part by the transmission of rotation to each upper roll of a pair by friction through the material of the web which is passed through successively lower nips. The coating units 100, 104 comprise a rotated roll 22 dipping in a pool 23 of adhesive a doctor blade 25 being provided. Edge wipers 48 remove adhesive 49 from the roll 22 to keep the edge of the web adhesive-free.
